Welding Stress Corrosion Cracking: Understanding the Hidden Threat

By Engineering Department | Arc Machines, Inc. Weld Defects

Stress corrosion cracking is an issue of increasing concern. Occurring in high heat service environments or highly corrosive service environments, or a combination of both this is a type of intragranular grain boundary cracking that can seriously shorten the lifespan of even high specification metals like Inconel or other nickel…

Orbital welding solves some common wire feed welding problems, but has a few of its own.

The Top 4 Orbital Wire Feed Welding Problems—And What to Do About Them

By Engineering Department | Arc Machines, Inc. Pipe Welding, Weld Defects No Comments

Because of the speed of wire feed welding, welders coming from more demanding manual processes tend to enjoy their first time using a wire feed process like gas metal arc welding (GMAW) or flux core arc welding (FCAW). Pairing a wire feed with automated orbital welding offers a similar experience….

Orbital weld defects are similar to those found in manual welding and have similar causes.

How to Avoid Common Orbital Weld Defects

By Engineering Department | Arc Machines, Inc. Orbital Welding, Weld Defects No Comments

Many of the same defects common during traditional manual welding also occur during orbital welding as well. These include contaminated welds, lack of fusion, and poor formation of the weld itself. One big difference between orbital welding and manual welding is that in manual welding it is possible to compensate…
